This Plum app review is based on three months of genuine use. We set up Plum to run alongside our existing auto-saver to see whether it would earn a permanent place on our home screen. Plum is one of those apps that does a lot and wants you to know it. Auto-saving, round-ups, investing, bills management, cashback offers, interest-earning pockets. After three months of testing, here's whether all that activity translates into genuinely saving more money.

What Is the Plum App?

Plum is a UK fintech app that uses an algorithm to analyse your spending and automatically move affordable amounts into savings. On top of auto-saving, it offers round-ups, interest-earning pockets, investing (stocks, funds, and ISAs), a pension (SIPP), and bills management. It's available on iOS and Android, and has been downloaded by over two million people.

Plum Fintech Limited is registered with the Financial Conduct Authority (FRN: 836158), and its investment arm, Saveable Limited, is authorised and regulated by the FCA (FRN: 739214). You can verify both entries on the FCA Register.

First Impressions of the Plum App

Signing up took about five minutes. You download the app, enter your details, and connect your bank account via open banking. Plum only gets read-only access to your transactions, so it can't move money without your permission through a direct debit you set up.

The dashboard is where things get busy. There are tiles for saving, investing, pockets, cashback, bills, and a persistent nudge to upgrade to a paid plan. If you prefer apps that do one thing well and stay out of your way, Plum's visual density might feel like a lot at first. That said, once you find your way around, the layout is logical enough. It just takes a few sessions to settle in.

Setting up auto-saving was straightforward. You choose your "mood" (essentially how aggressively you want Plum to save), and within a few days the algorithm makes its first sweep from your bank account.

Auto-Saving: The Core of the Plum App Review

At the heart of this Plum app review is the auto-saving algorithm. Plum analyses your income and spending patterns and moves what it thinks you can afford. You control the intensity through mood settings ranging from "Shy" (very cautious) to "Beast Mode" (very aggressive).

Our experience: the default "Normal" setting was more aggressive than expected. In the first month, Plum moved about £180 without us doing anything. That was more than anticipated, and we had to dial it down to "Chilled". Once adjusted, it settled at about £120 to £140 per month, which felt right.

If you're living pay cheque to pay cheque, start on the lowest setting. You can always increase it once you're comfortable. Plum will never leave you overdrawn (it only saves what it calculates you can afford), but "can afford" is still a judgement call. The algorithm doesn't know about irregular expenses like car insurance renewals or birthday presents, so keep an eye on things during the first few weeks.

Auto-saving is available on all plans, including the free Basic tier. On the free plan you get six Auto Savers (rules that trigger saves), rising to ten on paid plans. For most people, six is plenty.

Round-Ups: Where Plum Genuinely Shines

Every card transaction gets rounded up to the nearest pound, and the spare change is swept into savings. Plum calculates the total from the previous week's transactions and deposits the sum in one go, rather than after each individual purchase.

This is where Plum genuinely shines. The round-ups feel seamless. In our testing, they added about £30 to £40 per month. It's tiny amounts per transaction, but they compound into something meaningful over a few months. Over three months, round-ups alone contributed roughly £100 to our savings without any conscious effort.

Plum also offers "Pound-Ups", which deposit an extra £1 for transactions that are already whole numbers (like a £4.00 purchase). It's a nice touch if you want to accelerate things further. On top of those, there are gamified rules like the 52-Week Challenge (which builds savings week by week up to £1,378 in a year) and the Rainy Days rule (which saves a set amount whenever it rains in your area). They're fun additions, though we stuck with the core round-ups and auto-saves for simplicity.

Interest Rates and Savings Pockets

Plum offers several places to park your money, each with different rates and protections. Here's a breakdown as of April 2026:

The Primary Pocket earns no interest. It's essentially a holding area for money before you move it into an interest-earning pocket or investment. Money here is safeguarded under e-money regulations but is not covered by the FSCS.

The Easy Access Savings Pocket, provided by Investec Bank, pays 3.00% AER on the free Basic plan, rising to 3.63% AER on the Max plan (£14.99/month). These pockets are FSCS-protected up to £120,000 per person. Withdrawals take one working day.

The Cash ISA currently pays 4.61% AER (variable) across all tiers. However, that headline rate includes a bonus of 2.07% that only applies for the first 12 months. After that, the rate drops to 2.54% AER. That's a significant cliff, and it's worth knowing before you commit. Deposits are FSCS-protected up to £120,000.

The 95-Day Notice Pocket pays 4.08% AER but is only available on the Max plan. Also FSCS-protected via Investec Bank.

Plum Interest is a money market fund (BlackRock ICS Sterling Government Liquidity Fund) that tracks the Bank of England base rate. The projected yield ranges from 2.74% to 3.67% depending on your plan. This is an investment product, not a savings account. Your capital is at risk, and it is not covered by the FSCS.

The rates on the Easy Access Pockets are decent but not market-leading for a standard savings account. The Cash ISA headline rate is competitive at first glance, but always factor in that post-bonus drop. For a broader view of the best rates right now, see our best savings account UK guide.

If you already have savings with Investec, Citibank, QNB, or Lloyds (Plum's banking partners for different products), be aware that the £120,000 FSCS limit applies per banking licence, not per app. Check your combined exposure.

Investing with Plum

Plum offers investing within the app, including a Stocks and Shares ISA, General Investment Account, and a SIPP pension. You can invest in up to 3,000 US stocks and choose from up to 26 curated funds (depending on your plan tier). The funds are managed by providers like Vanguard and Legal and General, rebranded under Plum's own labels.

We haven't used Plum's investing features enough to review them properly. If you're looking at investing, we'd suggest dedicated platforms for greater control and lower fees. For a deeper look at your options, see our best investment ISA picks for 2026.

Capital at risk. The value of your investments can go down as well as up. You may get back less than you invest. This is not financial advice.

Free vs Paid: Is Upgrading Worth It?

Plum restructured its pricing in July 2025. The current tiers are:

Basic (free): auto-saving with 6 Auto Savers, Easy Access Savings at 3.00% AER, Cash ISA at 4.61% AER, Plum Interest at 2.74%, 1 customisable pocket, Stocks and Shares ISA, 2 free stock trades then £0.50 each, and a 0.60% management fee on investments.

Plus (£3.99/month): everything in Basic, plus 10 Auto Savers, 16 customisable pockets, 13 investment funds, lower trading fees (£0.15 per trade after 2 free), and a 0.45% management fee.

Boost (£7.99/month): everything in Plus, plus a Plum Visa debit card, Spend Insights, a better Easy Access rate (3.20% AER), 22 funds, and a 0.30% management fee.

Max (£14.99/month): everything in Boost, plus the 95-Day Notice Pocket (4.08% AER), the best Easy Access rate (3.63% AER), 26 funds, unlimited free stock trades, a 0.15% management fee, lifestyle perks (travel insurance, cinema deals, NordVPN), and priority support.

We used the free Basic tier for the full three months. It did everything we needed for auto-saving and round-ups. The premium features are nice-to-haves, not must-haves. Unless you're actively investing through Plum or need the higher savings rates, the free tier is genuinely generous.

The Max plan at £14.99/month is steep. The lifestyle perks (2-for-1 cinema tickets, travel insurance, coffee discounts) are valued at £74/month according to Plum, but only if you'd actually use them. For most people, the free plan does the heavy lifting.

The App Itself

Plum's UX is colourful, feature-rich, and busy. There are a lot of tiles, menus, and options. For some users, that density is a strength: everything in one place. For others, it's clutter. We found ourselves wanting a simpler layout more often than not, though the app did grow on us as we learned where everything lived.

Reliability was generally good during our testing period. We didn't experience any crashes, and the auto-saving ran without issues. Notifications are manageable, and you can customise what Plum sends you. However, the upgrade prompts are persistent. Almost every section of the app includes a nudge to try Plus, Boost, or Max. It's not aggressive enough to be a dealbreaker, but it does get repetitive.

The app is rated 4.7 out of 5 on the Apple App Store and 4.6 out of 5 on Google Play. On Trustpilot, Plum holds a "Great" rating of 4.1 out of 5 from around 9,000 reviews. Common praise centres on the ease of auto-saving and how quickly small amounts add up. Common complaints mention slow customer support responses and confusion around interest rate structures, particularly the Cash ISA bonus rate that drops after 12 months.

Value for Money

On the free tier, Plum is excellent value. You get a capable auto-saver, round-ups, an FSCS-protected savings pocket at 3.00% AER, and a Cash ISA at 4.61% AER (for the first year). That's a lot for nothing.

The paid tiers are harder to justify unless you have a specific need. Plus (£3.99/month) makes sense if you want cheaper investing fees. Boost (£7.99/month) adds the debit card and better savings rates. Max (£14.99/month) is for power users who'll genuinely use the perks. If auto-saving and round-ups are your main goal, the free plan is all you need.

The Verdict

Cool Factor

★★★☆☆

3 out of 5

Plum works. The auto-saving algorithm is effective, the round-ups are the best we've used, and the free tier is genuinely generous. But the app tries to do too much, the premium upsells are persistent, and the interface takes time to get comfortable with. It's a solid auto-saving app that earns its place on your phone, but it didn't quite blow us away.

We also use Chip as our primary auto-saver. We'll be publishing a detailed Plum vs Chip comparison soon, so keep an eye out if you're deciding between the two.

Try Chip (£50 bonus)

Overall, 3/5 Cool. This Plum app review confirms it does the job, and the round-ups are a genuine highlight. But it doesn't quite hit Stone cold because the app is cluttered, the premium nudges are annoying, and we found ourselves reaching for a simpler interface more often. If you want an everything-app for your finances, Plum delivers. If you want something quieter, there are cleaner alternatives.

Plum App Review: FAQs

Is the Plum app safe in the UK?

Yes. Plum Fintech Limited is registered with the FCA (FRN: 836158), and its investment arm Saveable Limited is authorised and regulated by the FCA (FRN: 739214). Money in Easy Access Savings Pockets and the Cash ISA is held with Investec Bank and protected by the FSCS up to £120,000 per person. However, money in the Primary Pocket is safeguarded under e-money regulations rather than FSCS-protected, and Plum Interest is an investment product where your capital is at risk.

How does Plum auto-saving work?

Plum connects to your bank account via open banking and analyses your income and spending patterns. It then calculates what you can afford to save and moves that amount via direct debit every few days. You choose your "mood" setting to control how aggressive the algorithm is, from "Shy" (very cautious) to "Beast Mode" (very aggressive). You can pause auto-saving at any time.

Is the Plum app free?

The Basic plan is completely free and includes auto-saving, round-ups, one savings pocket at 3.00% AER, and a Cash ISA at 4.61% AER. Paid plans start at £3.99/month (Plus) and go up to £14.99/month (Max), adding features like extra pockets, higher savings rates, cheaper investing fees, and lifestyle perks.

Is my money protected in Plum?

It depends where your money sits. Easy Access Savings Pockets and the Cash ISA are held with Investec Bank and protected by the FSCS up to £120,000 per person per banking licence. Your Primary Pocket balance is safeguarded under e-money regulations but not FSCS-covered. Plum Interest is an investment product (a money market fund) and your capital is at risk. Always check which product your money is in.

Can you withdraw money from Plum instantly?

Withdrawals from your Primary Pocket are near-instant (typically within 30 minutes). Withdrawals from interest-earning savings pockets take one working day. The 95-Day Notice Pocket requires 95 days' notice, as the name suggests. There are no withdrawal fees on the free plan, though the Cash ISA's bonus interest rate may drop if you make more than four withdrawals or your balance falls below £100.

Is Plum regulated by the FCA?

Yes. Plum Fintech Limited is registered with the FCA as an Account Information Service Provider (FRN: 836158). Saveable Limited, which provides Plum's investment and ISA services, is authorised and regulated by the FCA (FRN: 739214). You can verify both on the FCA Register.

What interest rate does Plum pay?

As of April 2026: Easy Access Savings pays 3.00% to 3.63% AER depending on your plan. The Cash ISA pays 4.61% AER (variable), but this includes a bonus rate that drops to 2.54% AER after 12 months. The Lifetime ISA pays 4.06% AER. The 95-Day Notice Pocket pays 4.08% AER (Max plan only). Plum Interest (a money market fund, not a savings account) offers a projected yield of 2.74% to 3.67% depending on your plan, but your capital is at risk. All rates are variable and subject to change.

Does Plum have a Cash ISA?

Yes. Plum's Cash ISA is available on all plans, including the free Basic tier. The current rate is 4.61% AER (variable), though this includes a 12-month bonus rate of 2.07%. After 12 months, the rate drops to 2.54% AER. It's a flexible ISA, so you can withdraw and redeposit within the same tax year without using up your annual allowance. Deposits are FSCS-protected up to £120,000 via Investec Bank.
